Replace Your Car's AC Thermal Expansion Valve or Orifice Tube
Accurate Transmission, Inc.
Your car or truck's AC system is under extreme pressure and the thermal expansion valve or orifice tube monitors the amount of pressure and the temperature of your A/C system. It calculates the precise amount of refrigerant that can safely go into the evaporator. A failing expansion valve or orifice tube often causes a vehicle's air conditioner to blow hot air.
Replace or Repair
- Expansion Valves: Too much refrigerant causes your evaporator to get too cold whereas too little refrigerant would result in inadequate cooling. The expansion valve is a complex valve that regulates refrigerant flow. This process of metering the refrigerant adjusts the flow according to the temperature of the refrigerant in the evaporator coil. Talk to one of the pro mechanics at Accurate Transmission, Inc., as this part can be replaced on its own and does not require the entire replacement of the AC assembly.
- Orifice Tubes: Unlike the expansion valve, the orifice tube is a simple fixed device with no moving parts. It therefore cannot vary the flow of refrigerant into the evaporator, but rather causes a permanent restriction in the system. However, like the expansion valve the orifice tube regulates refrigerant flow through the system and filters debris which may come through in its screen. Often fixing a "bad orifice tube" requires replacing the entire evaporator assembly.

I had an issue with my SUV. I left it and the next day they took it for a test drive and could not find anything wrong. They volunteered to drive with me to duplicate the issue. They are extremely customer orientated, honest and willing to go the extra mile for you. Though they spent a day with my SUV and a about an hour driving with me and explaining what it could be, they did not charge me for their time or testing. They also did not pressure me into getting something fixed that didn't need repair right away. It's refreshing to find great customer service. They will have my business. Good people!
